Question

there are 27 red and 13 Blue coloured ball in the bag the van of the weight of the 1 red ball to the weight of the blue balls in the bag correct to two decimal places​

Answer 1

Answer:

Step-by-step explanation:

The percentage of the weight of blue balls  in the bag is 17.63%​

1) The ratio of weight of red and blue ball is given as 9:4

Let the weight of red ball be 9x and blue ball be 4x.

2) Total red balls: 27

weight of red balls :- 27*9x = 243x

3) Total blue balls: 13

weight of blue balls: 13*4x = 52x

4) Total weight of balls =  243+52  = 295 x

Given total weight is 65 kg

295x = 65 kg

x = 0.22kg

5) weight of blue balls would be 52x=  0.22*52 = 11.4576 kg

6) Percentage of weight of blue balls is :

(11.4576/65 )*100 = 17.627 or 17.3=63%
